Treehouse Guest TeacherHere's a checklist that might help:
- Do you have multiple versions of Ruby? Do you have rvm or rbenv installed? If so, you have to make sure you are installing the CocoaPod gem to the right version.
- Do you have the latest version of Xcode?
- Do you have multiple versions of Xcode? If you do, then use the xcode-select to select the latest version of Xcode.
- Finally, here's another workaround that helped others: https://gist.github.com/goshakkk/5763489

Treehouse Guest TeacherThe error you posted above says: "You have to install development tools first", which means that it cannot find a compiler.
Try this from the command line:
xcode-select --install
It will install the command line tools.
